The Linnets negotiated a difficult game and pitch at Stag Meadow to maintain an unbeaten record against non-league opposition which stretches back to August.
Lynn won �3,000 by knocking out Division One South & West side the Royalists in the delayed original tie, and earned a trip to Southern Premier rivals Mangotsfield in the first round proper on Saturday, December 16.
Lynn began a run of four successive Tuesday games in swirly conditions against gale-force winds on a surface which mixed mud, sand and grass.
This made the game a lottery.
They deserve much credit to prevail so soon after their huge FA Cup tie, and after going behind to a 33rd minute Michael Chennels effort.
Leading scorer Chennels (14 goals) outran Grant Cooper and fired past Shaun Marshall.

Lynn escaped when Mark Camm played a back pass to Marshall which got stuck in the mud. Marshall made some smart saves to keep the deficit, although Lynn also rained shots in. It was impossible for Lynn to play their natural passing game in the conditions, but they did well to lift themselves in the second half. They had three efforts ruled out for offside. Jack Defty missed an open goal with a header, while Alex Notman was denied in a one-on-one. The Walks outfit won a penalty for handball which was converted by Notman, who sent the home keeper Sam Mazurek the wrong way, on 71 minutes for the visitors to level. Three minutes later Grant Cooper went on one of his charges upfield from defence to hit the winner from inside the Windsor box.
